HOSPITAL-BED.

SPECIFICATION forming part of Letters Patent No. 244,612, dated July 19, 1881.

Application filed September-29,1880. Model.) 7

To all whom it may concern Be it known that we, FREDERICK W. J EN-.

SEN and CARL J. L. OLSEN, of the city, county,

and State of New York, have invented a new and useful Improvement in Hospital-Beds, of

which the following is a specification.

The object of our invention is to construct a bed especially adapted for hospital use, and convenient for giving all the necessary attentions to the sick.

Our improvements relate to the construction of the bedstead, and to devices combined therewith for the use of the sick person. We use an iron-frame bedstead, the bottom of which is formed by longitudinal rods sustained by crossbars and held in place by nuts at their ends. The head and foot boards are hung in slots in the side rails, so that they can be adjusted or swung down out of the way to give free access to the person on the bed. Combined with the bed we use a swinging arm carrying a vessel, which frame is fitted for being raised to carry thevessel through an aperture provided in the 1 bed-bottom and mattress. The bed is also fit- 2 5 ted with devices for automatically removing and replacing the cover of the vessel as it is moved to and from its place. All of these features are described hereinafter with reference to the accompanying drawings, forming part of this specification. 4

In the drawings, Figure 1 is a side elevation, partly in section, of our improved bed. Fig. 2 is a-planview of the same, and Fig. 3 is a vertical transversesection on line meof Fig. 2.

Similar letters of reference indicate correspondin g parts.

The frame of the bed consists of side bars, a a, end bars, 12 b, and intermediate cross-bars, c c, which are metal, and the frame is-supported on legs d. 'The bottom consists of small rods 6, which extend over cross-bars 0 and thropgh the end bars, b. The ends of rods 0 are fitted with nuts 6, by which the rods can be tightened and are held in place.

The head-board f and foot-board g are made as metal frames attached on rods h, that are fitted across thebed in slots iof the side bars, a. The boards f g are held upright by legs or projections f, that engage with notches g formed in the upper edges of side bars, a, and there are two notches, g, in each side bar, at the head, so that the board fcanbe moved inward over the mattress to support the'patient in a sitting position. The slotst' are made long, so that the boards f 9 can be turned down, as 5 5 shown in dotted lines in Fig. 1, whereby they V will be out of the way and surgical operations can be more readily performed.

From the bar a, at one side of the bed, rods k k depend, which rods are fitted with loose 6o sleeves l i, that carry arms m m, and the sleeves are also provided with handles 1 for their operation, as hereinafter described. The arm m, hung on red k, has its outer end formed with an upward projection to enterasocket of thevessel n, wherebythe vessel is held in an upright position on arm at and can be removed therefrom at will. The vessel n is provided witha sliding cover, a. The arm m, hung on red It, carries at its outer end a plug, 0, consisting of a tube, upon the upper end of which is fixed a pad of soft material.

At the center of the bed-bottom is fitted a tube, 19, large enough to receive the vessel 01., and the mattress q is formed with an aperture over the tube 1) and corresponding in size therewith. By this construction either the vessel n or plug 0 can be turned beneath the opening in the bed and then raised to extend through tube 10 and the aperture of the mattress. The plug is intended .to remain in the opening at all times when the-vessel is not required for use, to prevent irritation of the patient by the edges of the opening; but this plug may be dispensed with if not required. To hold the arms at m up, and sustain the vessel and plug,

a sliding spring-pin, r, is fitted at the side of the bed for engagement with notched lugs 19 on arms at m, as shown in Fig. 3. The cover it of the vessel is provided on its upper side 0 with a notched plate that forms undercut lugs n, and at the under side of the bed is an arm,

8, having at its outer end a. disk, t, (see detail Fig 4,) forming flanges that are held in position for passing beneath thelugsn of the cover 5 as the vessel is swung beneath tube 9, so that the cover is caught and held, thereby remov ing the cover from the vessel. There is also hung beneath the bed, on a stud, u, a double arm, a, moved in one direction by a spiral spring on the stud, which armis held in the path of the vessel 10, so as to be moved thereby.

Jan

The arm is formed with its shorter portion curved to the shape of cover a. The arm a is moved forward by the vessel as the latter swingsin,and its curved portion takes against the back of the cover when the vessel reaches its place. The arm it thus serves to retain the cover on the arm 8', and also, by its spring, start the arm m back when the vessel is drawn back. The cover slides to place on the vessel as the arm m returns, and the spring-arm u insures sufficientmovement of the arm to replace the cover, so that the vessel may not be left uncovered.

The sleeves l l and arms m m are to be operated by the handles 1?. The vessel may remain on the arm beneath the bed ready for use. To prevent the arm from swinging out accidentally the sleeve Z is notched, as shown at v, for engagementwith a brace,w, that con nects the lower ends of rods k It. By raising sleeve 1 the notch is cleared, so that the arm can be swung out for removal of the vessel.

The bed constructed as described is amply ventilated, and is convenient for use to both the patient and the attendants.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- 1. The bed-frame for hospital-beds, consisting of side bars, a, end bars, b, and crossbars 0, and having a bottom consisting of rods 0, provided with tightening-nuts a, substan tially as shown and described.

2. In hospital-beds, the head and foot boards f 9, provided with lugs f, and attached on rods h, combined with the slotted side bars, a, having notches g, substantially as and for the purposes set forth.

3. The combination, with a bed having a central opening, of arm m, carried by rod 70, and removable vessel upon the arm m, substantially as and for the purposes set forth.

4. The combination, with an apertured bed and mattress, of the arm m, carried by rod 70, and provided with plug 0, substantially as and for the purposes set forth.

5. In hospital beds, the fixed arm 8, provided with disk t, swinging arm m, vessel 11., and cover it, provided with lugs n combined for operating substantially as and for the purposes set forth.

6. The spring-arm a, hung on stud a, combined with the swinging arm m, vessel 10, cover 42., and devices for removing the cover, substantially as and for the purposes set forth.
